Compatibility with Motherboard and RGB Standards

The Arctic 360 RGB cooler uses specific RGB standards that must match the motherboard’s RGB header specifications. The two most common standards are:

Standard RGB (12V, 4-pin): Uses a 4-pin 12V header, controlling red, green, and blue channels simultaneously.
Addressable RGB (5V, 3-pin): Uses a 3-pin 5V header, allowing individual LED control for dynamic lighting effects.

If the cooler’s RGB cable is connected to a header with the wrong voltage or pin configuration, the LEDs will not function and may even be damaged.

RGB Standard	Voltage	Connector Pins	Compatibility Notes
Standard RGB	12V	4-pin (12V, R, G, B)	Common on older motherboards; not compatible with 5V ARGB headers
Addressable RGB (ARGB)	5V	3-pin (5V, Data, Ground)	Supports individually addressable LEDs; requires compatible headers and software

Before installation, verify the cooler’s RGB cable type and match it with the motherboard’s RGB header. Using adapters or RGB controllers designed for the correct standard can resolve compatibility issues.
